When I got the iPhone, I bought a new car stereo head unit with USB so I could get the audio from the phone playing through the car speakers, especially GPS instructions. But that only works when USB is the selected input. If I'm listening to the radio or XM through the AUX, I get nothing. I have to use the phone's little speakers to hear turn-by-turn instead.
So... I decide to get a bluetooth speaker so I can better hear phone calls and the GPS. Nice for phone, not so much for GPS.
Apparently there's an inherent delay in bluetooth and A2DP that causes the speaker to lag behind the audio. So what would be "turn left onto University Ave." becomes "...to University Ave.". If the instructions are too brief, I get no sound at all.
The Bluetooth seems like the best option to allow me to hear the turn-by-turn while still listening to XM, if not for the lag. It's not just an iPhone issue. Googling suggests it's a problem with any speaker or headset using A2DP.
Any ideas on how to get around this without just ditching the bluetooth speaker altogether?

Bah.
A little more googling after the initial post suggested the A2DP delay varied from device to device. I was using a Motorola Roadster, so I exchanged it for a BlueAnt S4. Tested on the same route I had issues on last night. All now working as intended.

I'm glad to hear that - I understand how Bluetooth works at a technical level, and was saddened to hear that manufacturers were designing devices in a way that didn't work, even though they should.
